Engineering Selection Recommendations

All three part numbers—8302401EC, 6N140A, and 6N140A/883B—are manufactured by Broadcom Limited and maintain active production status. Selection between these parts is based on availability and compliance requirements:

8302401EC: 1080 units in stock. ROHS3 compliant. Suitable for standard industrial applications requiring 1500VDC isolation with 4-channel Darlington output configuration.

6N140A: 1255 units in stock. ROHS3 compliant. Parametrically equivalent to 8302401EC with identical electrical and mechanical specifications. Higher inventory availability.

6N140A/883B: 4540 units in stock. ROHS3 compliant. Parametrically equivalent to 8302401EC with identical electrical and mechanical specifications. Highest inventory availability. The /883B suffix indicates compliance with MIL-STD-883 screening and testing requirements, suitable for applications requiring enhanced reliability documentation.

All three parts are REACH unaffected and carry MSL Level 1 (unlimited moisture sensitivity rating). Selection should prioritize availability and application-specific compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can 6N140A be used as a direct replacement for 8302401EC?

A: Yes. Both parts are manufactured by Broadcom Limited and maintain identical electrical parameters across all specified criteria: 4-channel configuration, 1500VDC isolation, 200% minimum current transfer ratio, Darlington output topology, 20V maximum output voltage, 40mA per-channel output current, and 16-DIP through-hole packaging. Mechanical and electrical compatibility is complete.

Q: What is the difference between 6N140A and 6N140A/883B?

A: Both parts are parametrically identical in electrical performance and packaging. The /883B designation indicates compliance with MIL-STD-883 military-grade screening, testing, and documentation requirements. Selection between these variants depends on application-specific reliability and traceability requirements.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts use identical 16-DIP (0.300", 7.62mm) through-hole packaging. Pin configuration, spacing, and mounting requirements are identical. No PCB redesign is required when substituting between these part numbers.

Q: Do all parts meet the same environmental and compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited) moisture sensitivity rating. Operating temperature range is -55°C to 125°C across all variants. Compliance documentation is equivalent.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and application-specific requirements. For standard applications, 6N140A or 6N140A/883B are recommended due to higher stock levels. For applications requiring MIL-STD-883 compliance documentation, 6N140A/883B is the appropriate choice.
